block numbers and swap legality?
I did a search and found that at least in CA the referee station determines swap elegibility by the casting number on the block. That is, if you have a '90 Camaro with a '70s 4-bolt they'd look at the casting # and fail you.
Is there any way for them to narrow down the year other than the casting number? I'm asking because I want to stick an '87 L98 engine in my 1990 car. I could track down all the proper emissions stuff, but I don't want to rebuild a motor and then get screwed over the matter of 3 years on a shortblock that's identical. Theoretically they should be indistinguishable since they'd have the same casting number, right?
Thanks for any help!

That will give you the year range of that perticular casting number. Some 350 1-piece run 87-89 others 87-90+ check it out and see.
